José Mourinho said he was prepared to make one of his two top goalkeepers “not happy” in the forthcoming Premier League season, even though he said the delicate decision leaves Chelsea in a “fantastic” situation.

Petr Cech made his comeback from injury in a 1-1 draw in Austria against RZ Pellets after three months out and impressed his manager, while Thibaut Courtois waits to regain fitness having only just returned to the club from his post-World Cup holiday. He was the Belgium No1 as the Red Devils reached the quarter-finals in Brazil.

Cech injured his shoulder in the Champions League semi-final at the end of April and Courtois returned to the club this summer from his loan spell at Atlético Madrid, meaning Mourinho will have to choose between one of them to start the Premier League campaign.

The Chelsea manager said: “My situation for the season is fantastic. To have Cech and Courtois, the best young goalkeeper in the world and one of the top three or five experienced keepers, for me and Chelsea it’s perfect. There’s no story. One will play and Chelsea will be in safe hands for good because both are very good players. One won’t be happy. But the Chelsea supporters will be happy and they’re more important than the players.”

Cech, 32, has been at the club for ten years but his position is under threat from the Belgium No1. Mourinho said: “The window is the window, but I’m so happy with the situation.” Mourinho gave a debut to Filipe Luís who joined last week for £15.8m from Atlético Madrid.
